Just thinking to myself that I needed to find some actual "part saws" for my ten series.
The Mac 1010-10a is from a yard sale I stopped by today, 25$ ofcourse it runs but I haven't seen the bore or piston.
The pro mac 10-10, I stopped by a scrap yard afterwards and the owner gave me it to me because it was locked up and the brake and clutch cover is busted . I pulled the starter and bar and chain, b/c were frozen together with rust.
Pulled the spark plug and PO installed a threaded insert which wasn't a terrible job but then sealed it up with jb weld and it came out with the plug. The rings were frozen to the bore but a few shots of deep creep and wiggling the flywheel back and forth the piston started sliding as it should.
So for a total of $12.50 a piece I have 2 McCulloch saws which one of them runs and the very good air filter on the Automatic is more than twice the amount of both.
